Abstract
Description
- This invention relates to a night vision enhancement system for motor vehicles and particularly to such a system incorporating head up display technology.
- It has often been proposed to use infrared cameras to produce images of a roadway revealing warm objects such as humans, animals or other sources of infrared radiation. This has the advantage of detecting such objects at night particularly if they are beyond the range of vehicle lights. Such systems have typically used a video monitor or the like to display the detected objects. A traditional monitor is bulky and difficult to locate in a convenient place for viewing, and requires the driver to look away from the roadway to observe the infrared image. The image would be quite small relative to the real roadway scene so that there could be some difficulty in accurately judging the distances of the objects being displayed. Thus if an object is not visible in the real scene, it is hard to determine its location.
- It is also known to employ head up display techniques to project instrument images or vehicle parameter data onto the vehicle windshield or other combiner so that the display is in or immediately adjacent to the driver's line of sight. Such displays have been quite small relative to the roadway scene due to the limited space available for the required image source and projection mirrors.
- The present invention seeks to provide an improved night vision system.
- According to an aspect of the present invention, there is provided a night vision system for a motor vehicle as specified in claim 1.
- The preferred embodiment provides enhanced night vision by infrared imaging in the line of sight of a vehicle driver. Object images may be displayed from an infrared source so as to have a one to one ratio with real objects observed by the driver.
- The preferred embodiment includes an infrared sensor or camera mounted on a vehicle to view the roadway in front of the vehicle and generate a video signal representing the thermal image of the roadway, a video processor for improving characteristics of the video signal, and a head up display (HUD) having a video display responsive to the video signal, and an aspheric mirror for reflecting the display image onto the vehicle windshield or other combiner so that the vehicle driver can view a virtual image of the display image which appears to be in front of the vehicle. The optical parameters of the camera and of the HUD are preferably chosen to provide a 1:1 ratio of the image and the real scene observed by the driver.
- By placing the image directly in the driver's field of view the image can be superimposed on the real scene. Then, warm objects in front of the vehicle will be highlighted if they were illuminated by the headlight beam, and they will be displayed in proper relationship to illuminated objects even if they are beyond the range of the lights. Alternatively, the image may be directed a few degrees below the primary field of view so that the infrared image appears just below the real scene. The latter approach is easier since no image registration is necessary as it is for the superimposed images. Still, by virtue of a 1:1 image ratio, the real position of a warm object shown in the HUD display can be readily determined.
- In the infrared camera, due to the high cost of lenses suitable for infrared, focusing mirrors are used for the camera optics, and these tend to introduce image distortion. In one design, for example, otherwise horizontal lines tend to droop at both ends to produce a "frown effect". The aspheric mirror is designed to correct for that distortion. The aspheric mirror has previously been used to compensate for distortion due to windshield curvature, each style of windshield requiring a custom designed mirror. In this embodiment, the aspheric mirror design takes into account the camera distortion as well as the windshield distortion.
- The video processor is preferably designed so that it can be set to an "object detect" mode, if desired, to select only the signals from the warmest objects so that those objects will be displayed and other background objects will be suppressed. This will attract the driver's attention to the warmest objects which are generally the most important ones to be made aware of. By driver selection, however, a full contrast mode can be employed to display all the infrared information.
- An embodiment of the present invention is described below, by way of example only, with reference to the accompanying drawings, in which:
- Figure 1 is a schematic view of an embodiment of night vision enhancement system mounted in a vehicle;
- Figure 2 is the display portion of the system of Figure 1;
- Figure 3 is a top view of a roadway scene showing an infrared camera view of the scene;
- Figures 4 and 5 are illustrations of driver views of night vision enhancement display for two different display configurations;
- Figure 6 is a block diagram of a camera and display portion of the system of Figure 1; and
- Figure 7 is a graph of video signals according to selectable modes of operation.
- Referring to Figures 1 and 2, a
vehicle 10 is equipped with night vision apparatus comprising a front-mountedinfrared camera 12 or sensor which has a standard RS-170 video output signal, avideo processor 14 connected to thecamera 12 output, and a head up display (HUD)system 16 including an image source ordisplay 18 connected to the video processor output, and anaspheric mirror 20 which reflects the display image to thevehicle windshield 22, creating avirtual image 23 for viewing by thevehicle driver 24. Thedisplay 18 recreates the image in shades of grey. A separate combiner may be used instead of the windshield. TheHUD 16 is installed beneath thevehicle dash 26 which has an upper opening for light passage to the windshield. - The
infrared camera 12 preferably has a field of view of about 12 degrees or more horizontally and a smaller vertical field in the range of 6 - 9 degrees. While a camera having a wider angle may be used, only the image portion within the prescribed angle should be displayed for optimum effect. The horizontal view of the camera is illustrated in Figure 3 which depicts the vehicle on a two lane roadway. The limit of the headlight range is indicated by thedashed line 28. Afirst person 30 is shown in the lane of the vehicle within the headlight range and asecond person 32 is shown beyond the headlight range. - The
infrared camera 12 comprises a sensing element operable at room temperature (i.e., cryogenic cooling is not required) and focusing optics which use mirrors instead of lenses. The camera senses the thermal pattern or the image of infrared radiation in its field of view. Preferably the camera should be sensitive to radiation in the mid-infrared range or about 8-12 micrometres. Since hot objects radiate more infrared energy then cool objects, the hot or warm objects will yield stronger signals. Thus animals, including humans, which are warm show up prominently in the image. Other heat emitters such as vehicle lights and exhaust pipes or traffic lights also show up very well. By presenting this information to the vehicle driver, the direct visual image of the roadway and its environs is augmented. - A common side effect of camera mirror arrangements is some image distortion, particularly a drooping at each side of the image. The video signal output from the camera to the display transfers that distortion to the display image. To avoid misinterpretation of the display by the driver it is desirable to correct for the distortion. Accordingly, the
aspheric mirror 20 is shaped to compensate for that distortion as well as any distortion arising from the windshield curvature. - The
aspheric mirror 20 is positioned to project the image to thewindshield 22 or other combiner where it is reflected to thedriver 24 as a virtual image which appears to be just at the front of the vehicle. The size of the image is consistent with the real scene observed by the driver. For example, if an object subtends an angle of one degree in the real image, the virtual image will also subtend an angle of one degree. The location of the image may be low in the windshield, or just above the end of the headlight range in the windshield. It also may be registered with the real image; in that case the image should be projected a large distance in front of the vehicle to reduce parallax arising from the distance between the camera and the driver's eyes. In practice, using a camera having a 12 degree field of view (or using a 12 degree portion of a larger field), and an LCD display 81 mm wide, a 6 x magnification by the aspheric mirror created a virtual image having a 12 degree field of view, thereby affording a 1:1 ratio of the image to the real world scene. - Figure 4 represents the real and the display imaged seen by the driver for the Figure 3 condition. The real image 30' of the
person 30 illuminated by the vehicle headlights is visible to the driver but theperson 32 is invisible. Both figures are detected by the IR camera and displayed as virtual images 30'' and 32'' below the real image 30'. The Image 30'' appears to be the same size as the image 30'. Thus the driver is forewarned of the presence of thesecond person 32 in the roadway. Figure 5 illustrates the condition where the HUD image is superimposed on the real image thereby correctly placing the HUD image in the roadway. This technique is more difficult to implement due to concerns of parallax caused by the separation of the camera from the driver, and the normal movement of the driver's head. A very satisfactory display location had been found to be at the lower part of the windshield where the central ray of the image is 5 degrees below horizontal. - As shown in Figure 6, the
video processor 14 couples the video signal from thecamera 12 to theLCD display 18, each being subject to controls 38. The controls should be easily accessible to the driver by mounting on the steering wheel or the instrument panel. Voice activation is another potential technique for control operation. The controls may select image polarity at thecamera 12 to establish hot objects to be either white or black. The full contrast mode or object detect mode may be selected at thevideo processor 14. This is accomplished by passing the whole signal range for full contrast or suppressing weak (cool) signals to display only the warmer objects. Figure 7 shows in solid lines that low input video signals are suppressed for the object detect mode, while full contrast is shown in dotted line wherein the whole signal is passed to thedisplay 18. Grey limit adjustment is also made at theprocessor 14. Thedisplay 18 is controlled to adjust brightness, adjust image position, or to turn the image on or off. - It will thus be seen that the embodiment of night vision enhancement system described can provide both a very practical implementation as well as a very flexible system in terms of how the infrared image is presented in or adjacent to the driver's line of sight. The 1 x magnification permits an intuitive assessment of the virtual image and the relationship of IR images to the real world scene, thereby providing roadway information which is not normally available and presenting it in its most useful form.
